Upcoming presentation to provide the latest information for commercial and residential applications
As energy conservation codes continue to become more stringent, the glazing industry is looking ahead to new technology, including the transition from double to triple insulating glazing units (IGUs) in colder climates. According to NGA’s energy code consultant Tom Culp of Birch Point Consulting, “There are a number of considerations with moving to triple glazing including cost, manufacturing changes, frame modifications, weight and more. There are significant efforts underway to ease the transition, whether that is using traditional triple glazing or the newer concept of ’thin triples’ using a thin glass middle lite.”
Thin triples look to achieve the next-levelsimilar thermal performance of traditional triple IGUs, but deliver a product that is not as heavy, not as wide, and will fit in the existing pocket of a normal sash. “With the thin triple, you get about an R-8 center of glass,” says Selkowitz. “You’ve gotAnd if you have a slightly larger wider glass package, you can put add two pieces of thin triple glass (making a quad IGU) and get R-14 center of glass. … This is great news as it offers new opportunities for glass to provide improved thermal comfort, reduced HVAC size and deeper energy savings.”
At the NGA Glass Conference: Miramar Beach January 24-26, Selkowitz will present considerations for the practical application of thin triples in commercial and residential construction.
The presentation sponsored by Pilkington|NSG, will focus on thin triples, with specifics about potential energy savings, embodied and operational carbon numbers, new opportunities for using thin glass for retrofit applications, as well as structural, impact and safety testing results of thin triples. Register for the NGA Glass Conference: Miramar Beach to participate in this discussion.
